case class TahoeLogFileIndex(spark: SparkSession, deltaLog: DeltaLog, path: Path, snapshotAtAnalysis: SnapshotDescriptor, partitionFilters: Seq[Expression], isTimeTravelQuery: Boolean) extends TahoeFileIndex with Product with Serializable

A TahoeFileIndex that generates the list of files from DeltaLog with given partition filters.

NOTE: This is NOT a TahoeFileIndexWithSnapshotDescriptor because we only use snapshotAtAnalysis for actual data skipping if this is a time travel query.

    Returns (i) tuples of partition directories to their respective AddFile actions and (ii) a collection of matched AddFiles. The matched AddFiles are those that meet the criteria set by the partition and data filters. Essentially, this is a collection of all the files associated with the identified partitions.

    Returns all matching/valid files by the given partitionFilters and dataFilters. Implementations may avoid evaluating data filters when doing so would be expensive, but *must* evaluate the partition filters; wrong results will be produced if AddFile entries which don't match the partition filters are returned.
